Niobec has been using the open stope mining method. The underground mine extracts over 2.3 million tons of ore which, once transformed, produces some 5000 tons of niobium annually. To break the ore, vertical holes, with a diameter of 17 centimetres (6.5 inches) are drilled off filled with explosives and detonated.
NIOBIUM ORES : Niobium mostly occurs as an oxide and in combination with tantalum. Pyrochlore[(Na, Ca)2Nb 2 O6F] and columbite [(Fe,Mn)(Nb, Ta) 2 O 6] are the major mineral ores of niobium, which constitute niobate, tantalate, iron, and manganese in definite proportions.Pyrochlore usually occurs in carbonatites and in pegmatite derived from alkalic …
Those companies that mine pyrochlore convert the niobium oxide units into HSLA ferroniobium through the aluminothermic reduction process or by reduction in an electric arc furnace. CBMM has installed capacity for the production of a high purity oxide that can be used to produce vacuum grade ferro- and nickel-niobium as well as niobium metal ...
